It depends on whether you actually work to heal those wounds or not. If you just float around and expect things to resolve itself, I don't think it usually matters if you give it 30 years. An online coach (by the name Life Coach Stockholm) I spoke with a few times told me that if I wanted to heal my inner wounds, I had to start work with the energy that had stuck in various parts of my body. I think you have to go deep and process the feelings behind the wounds and see which memories and triggers are associated with that wound. Then you should find a good coach who could provide the right tools for you.
